The results showed that Pb, Cd and Cu in the leaves of plants were positively related to their concentration in air significantly. The content of heavy metal in plant leaves was obviously associated with the heavy metal properties, pollution conditions and tree species. Platanus hispanica had a higher accumulation in Pb, While Populus deltoides in Cd and Cu.

研究表明，植物叶片中重金属Pb、Cd和Cu的累积量与大气中Pb、Cd和Cu的相对含量呈显著正相关；所调查绿化树种叶片的重金属含量因重金属种类、采样区和树种的不同具有明显差异，悬铃木叶片累积Pb的能力最强，而杨树叶片对Cd和Cu的累积能力最强。

通过对烟台市区不同大气污染区域绿化植物叶片中重金属Pb，Cd，Cu，Zn富积量和大气与土壤中相应重金属的含量研究分析发现，植物叶片中重金属Pb，Cu和Zn的富积量与大气中Pb，Cu和Zn的相对含量呈显著的正相关，而植物叶片中Cd的富积量与大气中重金属的相对含量相关不显著。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
